Passengers of high-speed trains might be exposed to relatively high sound levels, compared to those inside conventional trains. In particular, sound levels inside Chinese high-speed train compartments may reach values as high as 80 dBA. Because traveling times are usually substantial in China, a wider variety of social activities occurrs inside the trains and more noise related problems for pas...

With given trip time on each section, conventional train energy-efficient operation problem optimizes the reference speed profile such that the energy consumption for tracking the profile is minimized. Alternatively, this study aims to solve its anti-problem that minimizes the trip time under certain energy constraint, namely the train energyconstraint operation problem. In particular, this stu...

This paper illustrates the phenomenon of the critical speed in the range 100300 km/h. A real explanation and a precise calculation of the critical speed seems to rest an unresolved problem in many cases. Some authors, analogous to “Mach effect”, have attributed this phenomenon to the reaching the Rayleigh wave speed of substructure by trains. But this explanation can’t be thorough in many cases...

The most popular dispatching rule for double-track segments is to dedicate one track for trains traveling in one direction. However, today passenger trains are able to travel at a much faster speed compared to freight trains, but the limitation of the rail infrastructure makes it more cost effective to allow the passenger trains to share some portions of the railway tracks with the slower freig...
